Indaco carminio

Descrizione:
Indaco carminio, noto anche come acido indigotindisolfonico, è un colorante sintetico caratterizzato dal suo profondo colore blu. È comunemente usato in varie applicazioni, incluso come agente colorante alimentare (E132), in prodotti farmaceutici e in colorazioni biologiche. La formula chimica di Indaco carminio è C16H8N2Na2O8S2, il che indica che contiene gruppi di sodio e sulfonato, che ne migliorano la solubilità in acqua. Questo composto mostra un'eccellente stabilità in condizioni normali, ma può degradarsi se esposto a forti acidi o basi. Indaco carminio è noto per la sua capacità di assorbire luce nello spettro visibile, rendendolo utile in saggi colorimetrici. Inoltre, è stato utilizzato nella diagnostica medica, in particolare in procedure come i test di funzionalità renale. I dati di sicurezza indicano che Indaco carminio è generalmente considerato sicuro per l'uso in alimenti e prodotti farmaceutici, sebbene alcune persone possano sperimentare reazioni allergiche. In generale, il suo colore vibrante e la versatilità rendono Indaco carminio un composto prezioso in vari campi.

  • Indigo carmine (Standard)

    CAS:
    Indigo carmine (Standard) is the standard for Indigo carmine (T19755). Indigo carmine (Fd&c blue no. 2) is a synthetic blue food colorant; in addition to being a dye, it can directly serve as a model substrate in visible-light photocatalytic degradation research, used to evaluate the degradation performance of photocatalytic systems such as TiO₂, CeO₂, and g-C₃N₄ toward organic dyes. In bacteriophage research, Indigo carmine shows selective inactivation against DNA phages P001, T4, T1, T7, and λ, with EC₅₀ of 0.006-0.105 mg/mL, while no obvious activity was observed against RNA phage MS2. Indigo carmine can selectively bind double-stranded DNA and promote phage genome release and capsid deformation, and under specific experimental conditions can reduce phage titers by up to approximately 7-log. Indigo carmine can therefore be used in research on photocatalytic dye degradation, phage inactivation, and DNA interactions.
